Image Stitch
Combine two overlapping scans into a single image. Uses cross-correlation to align the images and blends the overlap region. Equivalent to Gwyddion's merge.c / stitch.c modules.

Description |
| direction |
dropdown |
auto |
How field_b is positioned relative to field_a: right, below, or auto (determined by cross-correlation) |
| blend |
dropdown |
linear |
Overlap blending: linear (smooth transition) or none (hard cut) |
Notes
- Auto direction uses cross-correlation to determine whether field_b is to the right or below field_a.
- Linear blending produces a smooth transition in the overlap region, avoiding visible seams.
- Both fields should have the same pixel size (dx, dy) for correct physical dimensions in the output.
- The output field's physical dimensions are updated to reflect the combined area.
